  - Upcoming Unsifted Videos - active video submissions that neither are published to the front page nor archived to the submitter's personal queue
- Have you seen a really funny, surprising, scary, interesting, cute or in any other way extra good quality video?
  Post and share it here - VideoSift is the best video aggregator on the Web, where we share, discuss, promote, and interact with the best videos out there on the web. Post it here, and share it with the large community of video-interested users. And - you are guaranteed to find more very good videos here already!
  Mind you, we only share videos you discover that someone else has made; if you "self link," by posting a video you have made, have posted or have interests in, you risk the ban hammer - read the posting guidelines before posting. The sift is NOT for promoting your own videos - it is for sharing videos others have made.

http://www.nasa.gov/feature/goddard/lasers-path-through-icesat-2

ICESat-2's instrument, ATLAS, is designed to measure heights on Earth. ATLAS has three main tasks: transmitting a pattern of six laser beams, collecting the laser photons that return to the satellite after reflecting off Earth, and recording the travel time of those photons. First up – transmitting the laser. In this video, optical engineer Tyler Evans illustrates how the laser is transmitted from the ATLAS instrument to the ground.
